Influence of the composition of essential oils on their antioxidant and antiradical properties

Influence of the composition of essential oils on their antioxidant and antiradical properties The antiradical and antioxidant properties of essential oil mixtures (EOMs) with various compositions in model systems of hexanal autooxidation, thermal oxidation of methyl linoleate and β-carotene, and in a reaction with the stable diphenylpicrylhydrazyl radical were studied and compared. It was found that all studied EOMs exhibited antiradical activity. The highest antiradical activity was observed for an EOM containing monoterpene hydrocarbons as the main components (the phenol content was low). The antioxidant activity of all EOMs was from 60 to 98% and depended on the model system composition and the method of assay. The mixture with the maximum phenol content exhibits the highest antioxidant activity level in the hexanal autooxidation system. EOMs with a high content of phenols and α- and γ-terpinenes were the most efficient antioxidants in the β-carotene model system. The study confirmed the possibility to vary the antioxidant and antiradical properties of essential oils by preparing their mixtures with a specific composition. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals

Abstract

The antiradical and antioxidant properties of essential oil mixtures (EOMs) with various compositions in model systems of hexanal autooxidation, thermal oxidation of methyl linoleate and β-carotene, and in a reaction with the stable diphenylpicrylhydrazyl radical were studied and compared. It was found that all studied EOMs exhibited antiradical activity. The highest antiradical activity was observed for an EOM containing monoterpene hydrocarbons as the main components (the phenol content was low). The antioxidant activity of all EOMs was from 60 to 98% and depended on the model system composition and the method of assay. The mixture with the maximum phenol content exhibits the highest antioxidant activity level in the hexanal autooxidation system. EOMs with a high content of phenols and α- and γ-terpinenes were the most efficient antioxidants in the β-carotene model system. The study confirmed the possibility to vary the antioxidant and antiradical properties of essential oils by preparing their mixtures with a specific composition.
